Environment

Release : 21.0.4

So far this problem has only been detected on a systems with a DB2 database

Cause

The AE sends the wrong command to the DB: "TRUNCATE TABLE XEVT5;IMMEDIATE" 
There is a wrong semi-colon before IMMEDIATE.

Resolution

This is a defect and will be fixed in a future version of the product.

Note that there is NO impact unless AAI is used.
